    Examples

    Copy a disk to another disk via mirroring:

    Create the initial disk, plex, volume, and filesystem:
    test1[root]182: vxdg init bob_dg c0t12d0=c0t12d0
    test1[root]183: vxassist -g bob_dg make bob_vol 1000m
    test1[root]184: mkfs -F vxfs /dev/vx/rdsk/bob_dg/bob_vol
    version 6 layout

    largefiles supported
    test1[root]203: mount -F vxfs /dev/vx/dsk/bob_dg/bob_vol /vxd

    Create new disk for mirror:
    test1[root]204: vxdisksetup -i c0t0d0 publen=2048
    test1[root]205: vxprint
    Disk group: bob_dg

    TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0

    sd c0t12d0-01 bob_vol-01 ENABLED 2048000 0 - - -

    Add disk to dg:
    test1[root]206:
    vxdg -g bob_dg adddisk c0t0d0=c0t0d0
    test1[root]207: vxprint
    Disk group: bob_dg

    sd c0t12d0-01 bob_vol-01 ENABLED 2048000 0 - - -


    small, remove and recreate c0t0d0, this time defining public size (this is a 2G disk):

    test1[root]208: vxdg -g bob_dg rmdisk c0t0d0
    test1[root]209: vxdisksetup -i c0t0d0 publen=2048000
    test1[root]210: vxdg -g bob_dg adddisk c0t0d0=c0t0d0
    test1[root]211: vxprint

    pl bob_vol-01 bob_vol ENABLED 2048000 - ACTIVE - -
    sd c0t12d0-01 bob_vol-01 ENABLED 2048000 0 - -


    Add subdisk and plex and then attach:
    test1[root]212: vxmake -g bob_dg sd c0t0d0-02 c0t0d0,0,2048000
    test1[root]213: vxmake -g bob_dg plex bob_vol-02 sd=c0t0d0-02
    test1[root]214: vxplex -g bob_dg att bob_vol bob_vol-02

    test1[root]215: vxprint

    pl bob_vol-02 bob_vol ENABLED 2048000 - ACTIVE - -
    sd c0t0d0-02 bob_vol-02 ENABLED 2048000 0 - - -

    Mirror is complete, now detach original plex (1G took about 5 minutes to mirror):
    test1[root]217: vxplex -g bob_dg det bob_vol-01
    test1[root]218: vxprint

    Summary of plex states


    State Description Comments
    CLEAN Plex is up to date the volume is shutdown When the volume is started other plexes can sync from this
    ACTIVE The plex is active Plex is working in the volume
    STALE Plex needs to be resynced Plex must be synced with other plexes to make it active
    EMPTY No data on the plex or veritas does not know what state the data is in All plexes are this state at creation time may be for
    OFFLINE The pex is not currently participating in the volume When brought back on line the plex goes into a stale state
    IOFAIL The plex is detached from the volume The only way to fix this is to replace the failed disk but veritas can still read the private region on the disk
    NODEVICE No disk access recorded The disk can not be read at all
    REMOVED Disk device for the plex is removed The disk has been manually removed


    hanging state of plexes

    Random TIPS

    MANAGING inetd SERVICES
    Become superuser or assume a role that includes the Service Management Profile.
    List the properties for the specific service.
    # inetadm -l FMRI
    Change the property for the service.
    # inetadm -m FMRI property-name=value
    Example:
    # inetadm -m network/telnet tcp_trace=TRUE
    # inetadm -l network/telnet
